Abstract
The digestive organs were examined in 18 Svalbard reindeer and 17 domestic reindeer from northern Norway. The main difference was that the Svalbard reindeer had a relatively larger cecum/colon complex compared to the whole digestive system and to the body wt than the Norwegian animals. In Svalbard reindeer this system relative to the whole digestive system was larger in animals during winter than in animals shot in summer. No such seasonal variation was noted in Norwegian reindeer. The findings are discussed in relation to the ecology of the Svalbard reindeer. The development of a large cecum/colon complex in Svalbard reindeer may allow for enhanced absorption of water, ions and products of cecal fermentation when reindeer consume foods of extremely low digestibility such as mosses.
